Maintenance of high-precision cold drawn tubes in use
In order to prevent it from rusting, its surface and environment must be clean first, otherwise it will be easily corroded and produce some chemical reactions. When removing rust, pickling can be used to remove rust. Generally, many workers use chemical principles and electrolysis to remove rust. But if a chemical reaction is used to treat rust, workers must wear protective equipment before cleaning to prevent their bodies from being injured by chemical elements. Generally, chemical acid is not used to treat cold drawn pipes, because although chemical pickling has a good rust removal effect, chemical acid will also have an impact on the environment and may also affect soil quality.
